ABSTRACT:
A method and device for processing a body liquid specimen used for diagnostical examination. The specimen is brought to settle for a predetermined time in a first chamber of a container which has a second, separate chamber containing a certain amount of a fixative, whereupon a portion of the specimen containing a predetermined amount of a concentrate having high concentration of settled body cells is separated and confined in a third chamber, which is formed by partitioning off a portion of the first chamber. Thereafter the remaining body liquid is removed from the container, and said second and third chambers are interconnected in order to form a common, sealed chamber in which the concentrate is mixed with the fixative.
